因此，我有一个页面，用户可以在该页面上查看某个项目，在该页面上，他可以看到倒数计时器上的剩余时间（在js脚本中完成），并通过以下方式对该项目进行出价点击“出价”按钮。这样，增加了对该项目的投标时间。因此，当他这样做时，他会自动重定向到同一页面，并且所有内容都将重新加载，并且计时器会正确显示递增的时间。但是，例如，其他用户也可以出价，那么当其他用户出价时，该特定用户还需要查看页面上增加的时间。我正在尝试通过Pusher和Echo做到这一点。到目前为止，Pusher和Echo运行良好。我只需要某种方式就可以通过Echo在脚本中重新加载可变的截止日期，并在进行拍卖时再次进行时钟初始化。每当有人出价时，如何使该变量为自己赋予一个新值？ 这是我所做的
